Atlas Copco is introducing the Edge Drill Monitor, which is designed to show what is happening at the bottom of the hole during drilling.

Information about the hammer and the bit is displayed graphically in real time, allowing the operator to optimise the penetration rate of down-the-hole (DTH) drilling, maintain the correct degree of flushing and avoid tool breakage and consequent delays.

Edge, which has been developed jointly by 161 Atlas Copco and SPC Technology, is a device for continuous monitoring that can be fitted to all types of deep-hole drill rigs that use Secoroc DTH hammers.

“By isolating the hammer vibrations from all the other noise and analysing the frequency and amplitude of the drill bit hitting the rock thousands of feet below ground, we are able to provide the drillers with user-friendly real time information to optimize their drilling parameters,” said SPC Technology chief technology officer Ivo Henriksson. “In a recent customer evaluation programme, we reduced fuel cost per drilled footage by 10% and increased rate of penetration by 11% using the Edge.”

A sensor is mounted on the drill head or rotation unit, which is connected by a cable to the data capturing unit mounted on the rig. When the piston in the DTH hammer strikes the bit, it creates vibration which is captured, processed and interpreted, with the data transmitted to the PC. The PC displays this data on its 175mm screen. Any problems or unexpected changes are displayed in the graphical view in real-time with alerts when something out of the ordinary occurs. These spikes can then be interpreted, indicating scenarios such as the sudden presence of a new type of rock.

    Atlas Copco is launching its new top hammer surface drill rig, the FlexiROC T45, along with its new rock drill COP 3060. The company says the new rig, which follows the ROC F9 before it, was to be built on a tried and trusted platform that would provide high-availability and a wide area of use for both large and small applications. Field studies are said to show that the FlexiROC T45 with folding boom, depending upon rock conditions, uses only half as much fuel as its predecessor the ROC F9 using the same

    Rockmore International introduced its new A-series down-the-hole (DTH) hammers at bauma. The ROK 600A and 650A have been added to the company’s ROK range of hammers. The new 6inch-class (152mm) DTH hammers are the first models in the new A-class series. The A hammers feature new component designs that are said to demonstrate better performance and penetration rates suited to smaller compressors. “We are committed to developing new DTH hammer solutions that increase productivity and reduce drilling operatin

    January 6, 2017
    Synthetic diamond division of DeBeers, Element Six, has developed the 3D Percussive Diamond Insert (PDI) that it claims will radically cut costs in the mining drill industry. The 3D PDI uses the firm’s polycrystalline diamond technology to optimise wear and impact resistance properties, while improving penetration rates for the drill bit. The firm claims that tests of the drill insert show up to 10 times the drill life of a conventional tungsten carbide insert., greatly reducing costly rig downtime for serv
